Nintendo Switch Joy-Con Grey Set And Pro Controllers Super Mario Power A Grip

I don't not know much about these, but here is my best description: I have no way of testing these. The pro controller appears to hold a charge. The right joy con appears to hold a charge. The left joy con will light up when plugged up but does not appear to hold a charge. They are very clean. This is all I know about these controllers. From smoke free home. See pictures for details.
